The problem I've always had with VRS, is that we always practice the recovery from a 2,000' hover. Something tells me the aircraft is going to feel very different in a tailwind approach where you think you have enough airspeed,...and I'm curious as to how the Vuichard technique would handle that?
Anyway, I'll never have a fat enough logbook (or wallet) to crash an Astar, so I can only guess here, but my money is still on, that he came in too hot and waited too long to start slowing down.
